Aw, I totally understand the worry, checking discharge is such a normal mom thing to do, lalo na kapag may slight color changes. Please mention this to your OB at your next checkup, or call them sooner if you're feeling anxious about it, they'll give you peace of mind right away since any discoloration during pregnancy deserves a quick check, yan lang. Every pregnancy is different, kaya mas safe talaga na doctor lang ang sasagot dito, hindi kami. But I get why you're monitoring, you're doing great by being aware. Keep that appointment scheduled, and try not to stress yourself too much in the meantime, okay?
